Specification of Letters Patent. Patented NOV. 28, 1916 Application filed December 15, 1915. Serial No. 67,025.

To all whom it may concern:

Be it known that I, JAN KowAL, asubjec of the Emperor of Austria-Hungary, residing at Linoleumville, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Bell-Ringing Devices, of which the follow ing is a specification.

This invention relates to certain new and useful improvements in hell ringing devices.

The primary object of the invention is the provision of a bell adapted not only for sounding a notice and alarm but also serviceable in causing sounds or tones of different volumes.

A further object of the device is to provide.

a bell which is adapted to be sounded by manually swinging the same but which is also providedwith a plurality of playing hammers or clappers capable er sounding tones of diflerent volumes when striking different portions of the bell.

A still further object is to provide an attachment for a bell comprisingmeans for sounding tones of difi'ere'nt musical volumes upon contacting the bell, the latter having specially formed portions adapted for such contact of the said sounding means.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :Figure 1 is a vertical transverse sectional view through a bell forming a part of the present invention, some of the elements being shown in side elevation and broken away, and Fig. 2 is a top plan view thereof.

Referring more in detail to the drawings, the invention includes the swinging suspensionof a bell 10 by means of a clamp 11 secured to the shaft 12 by means of bolts 13, the said shaft being journaled through the upper end portions of oppositely-positioned posts 14. A sustaining threaded tang 15 centrally projecting from the flattened top 16 of the bell 10 extends through the clamp 11 and a transverse opening in the shaft 12,

clamp 11. A substantially the same having lock nuts 17 threaded thereon engaging the opposite sldes of the from a centrally arranged ring 19 upon the "inner face of the bell top 16. An outwardlyextending operating arm 20 projects from the clamp 11 arranged perpendicularly with usual form of'clapper-1'8. is. swingingly suspended withinzthe bell-10 upon the shaft 12 by means'of the operating arm 20 and that by reason of the tang 15 passing transversely through the shaft 12, the path of movement in the swinging there of is confined to a single arcuate plane, any relative movement of the bell longitudinally of the shaft 12 being rendered impossible.

A' sounding attachmentfor the bell "10 is provided whereby tones :of different volumes-may be played uponithe bell and jacent the bell 10 and substantially in .the

same horizontal plane as the bell top 16 when the bell is at rest. A separate hammer or tapper 24 is provided for the tones of different volumes desired to be produced by the bell 10, the said hammers having levers 25 of different lengths with their upper free ends pivoted Within central longitudinal slots 26 of the aforementioned frame arms 23. A leaf spring 27 is secured at one end beneath the inner free end of each of the arms 23 and resiliently bears against the face of the adjacent lever 25, normally positioning the said levers out of contact with the bell 10.

An operating pull cord 28 is provided for each of the hammers 24, the said cords passing over pulleys 29 journaled in the arms 23 and then extending to any convenient point to be grasped by the operator, it being understood that the free ends of the cords 28 may be attached to pivoted key levers not shown, ifdesired.

Outwardly-extending protuberances or projections 30 are provided in the sides of the bell 10 at points of contact of desirable ones of the sounding hammers 24, a better the same consists broadly of a frame 22 fixed? striking surface for the hammers being thus aiforded over the usual regular side wall of the bell.

In order to cause the tappers 24 to sound tones of difierent volumes, the outer face of the bell 10 is provided, as in the present instance, with a pair of spaced protuberances 30 as shown in Fig. 2 which are adapted to be selectively struck by the tappers 24 of two of the levers 25. The longer one of the levers 25 preferably strikes the plain face of the bell adjacent the edge 31 as is evident from an inspection of Fig. 1, thereby pro ducing a tone of different volume than the other levers produce by striking the protuberances.

By exerting a slight pull upon either of the cords 28 and then releasing the same, the lever and hammer which will be swung thereby will be allowed by reason of its own weight to contact the bell 10 and depress the ditional hammers and protuberances in a similar manner to those herein illustrated.

While the form of the invention herein shown and described is what is believed to.

be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is 1. A device of the class described, comprising supporting posts, a horizontal shaft journaled in said posts, a bell fixed to said shaft, protuberances positioned at different heights and in different radial planes in the side walls thereof, arms carried by one of the said posts and extending toward said bell in substantially the same horizontal plane as the top of the said bell when the latter is at rest, and a plurality of striking hammers of different lengths pivoted to the said arms and having paths of movement in line with the said protuberances.

2. A device of the class described, comprising a normally stationary bell having outwardly projecting protuberances in the sides thereof arranged at different heights and in different radial planes, supporting arms arranged adjacent the top of the said bell, striking members of difi'erent lengths having their upper ends pivoted to the said arms and adapted to be brought into contact with the said protuberances, springs for normally holding the striking members out of engagement with'the bell, and separate pull cords operating means for each of the striking members.

In testimony whereof I aiiix my signature.

JAN KOWAL.
